Step-by-step explanation:

The number of yards of fabric required for making 7 identical elf costumes is 15 3/4 yards.

A mixed fraction is represented with the quotient and the remainder. So, the combination of a whole number and the proper fraction is called a mixed fraction.

Eg: 2 3/4 where 2 is the quotient and 3 is the remainder.

It is given that,

Mrs. Henderson used 6 3/4 yards of fabric to make 3 identical elf costumes.

Then, for making 1 costume, it requires

1 costume = 6 3/4 ÷ 3

⇒ 27/4 ÷ 3

⇒ 27/4 × 1/3

⇒ 9/4 yards

Thus, making 1 elf costume requires 9/4 yards.

Then, for making 7 identical elf costumes, it requires

7 identical elf costumes = 7 × 9/4 yards = 63/4 yards

The obtained value is expressed in the mixed fraction form as

63/4 yards = 15 3/4 yards.

Therefore, 15 3/4 yards of fabric are needed for 7 identical elf costumes.

By using the least-squares regression line the equation will be y = 1.518x + 0.305.

Let us find the value of slope and y-intercept that suits the data y = mx + b

And then , we have to find the value of x² ,∑x,∑y,∑x²,∑xy also N

Then, we have to calculate the slope m

m = n∑(xy) - ∑x ∑y / n ∑(x²) - (∑x)²

= 5 X 236 -26 X 41 / 40 - 676

= 249 / 164

= 1.5183

Then , we hace to calculate the intercept b

b = ∑y - m∑x / n

= 41 - 1.5183 X 26 / 5

= 0.3049

After this we have to assemble it in the equation of line

y =mx + b

Therefore ,

y = 1.518x + 0.305

Answer:

\(8.3125\)pounds

Step-by-step explanation:

We are given that

Density of ethyl acetate at 25 degrees =\(0.902g/ml\)

We have to find the number of pounds in 133 ounces weigh.

To find the number of pounds in 133 ounces we will use unitary method

By using unitary method

We know that

1 ounce=0.0625 pounds

133 ounce=\(133\times 0.0625\)pounds

133 ounce=\(8.3125\)pounds

Hence,8.3125 pounds would 133 ounces weigh.

Answer:

6

Step-by-step explanation:

The straight line (at the bottom) measures a total of 180 degrees. So we can write an equation where the sum of all of the angles = 180:

180 = 5x + x + 54 + 90

90 comes from the square indicating a right angle.

Using that equation, solve for x.

180 = 5x + x + 54 + 90

First, combine like terms.

180 = 6x + 144

Then subtract 144 from both sides

36 = 6x

Divide both sides by 6 to isolate x

6 = x

So x = 6°

Answer:

Ahmed's profit is the difference between the selling price and the buying price:

Profit = Selling Price - Buying Price

Profit = £190,270 - £179,500

Profit = £10,770

To calculate the percentage profit, we need to divide Ahmed's profit by his buying price, and then multiply by 100 to convert the fraction to a percentage:

Percentage Profit = (Profit/Buying Price) x 100%

Percentage Profit = (£10,770/£179,500) x 100%

Percentage Profit = 0.06 x 100%

Percentage Profit = 6%

Therefore, Ahmed makes a 6% profit on the sale of the house.

Answer:

Step-by-step explanation:

The probability that someone who tests positive for opium use actually uses opium is  0.854  .

In the question ,

it is given that , the false positivity rate is 2% .

Let the sample size be of  100 .

11% of the people actually use opium = 100*0.11 = 11.

People who do not use opium = 100 - 11 = 89.

the test for opium has a 2% false positive , that is

= 2% of 89 = 89*0.02 = 1.78

So , the True negative = 89-1.78 = 87.22

the test for opium has a 5% false negative , that is

= 5% of 11 = 11*0.05 = 0.55

So , the True positive = 11-0.55 = 10.45

Probability is calculated by favorable/total.

Total (positive) = true + false = 10.45 + 1.78 = 12.23  .

Favorable (true) = 10.45

Probability is = 10.45/12.23 = 0.854

Therefore , the required probability is 0.854    .

The given question is incomplete , the complete question is

Suppose that a test for opium use has a 2% false positive rate and a 5% false negative rate. that is, 2% of people who do not use opium test positive for opium and 5% of opium users test negative for opium. furthermore, suppose that 11% of people actually use opium.

B. making an inference.

Step-by-step explanation:

The drama teacher's decision to add another performance time on Saturday is a result of making an inference based on the information that 80% of last year's sold-out plays occurred during weekend performances. By observing this pattern, the drama teacher infers that adding another performance on Saturday will likely attract a larger audience and increase the chances of having a sold-out show.

Step-by-step explanation:

the inside expression of an absolute value expression can be positive or negative, but the result is only the positive one.

therefore, for our example here the negative case would be

2.5x - 6.8 = -12.9

which gives us

2.5x = -6.1

x = -6.1/2.5 = -2.44

and the positive case would be

2.5x - 6.8 = 12.9

and that gives us

2.5x = 19.7

x = 19.7/2.5 = 7.88

The required equation for number of miles and years for the car is given as; y = 19000x + 41000

To represent a straight line on a graph consider two points namely x and y intercepts of the line. To find x-intercept put y = 0 and for y-intercept put x = 0. Then draw a line passing through these two points.

The parameters are;

Suppose the year 2020 represents x = 0.

The distance travelled per year can be taken as the slope of the linear  equation. Thus, slope = 19000.

And, the distance travelled by January 1, 2020 is 41000.

This tells us that for x = 0, y = 41000.

The linear equation in slope intercept form is given as;

y = mx + c

where;

m is slope

c is y-intercept

Substitute the corresponding values in the above equation to obtain,

y = 19000x + c

At x = 0, y = 41000

41000 = (19000 × 0) + c

c = 41000

Now, the equation can be written as,

y = 19000x + 41000

The median of the distances is M = 6.5 kilometers

Given data ,

To find the median of a set of numbers, we arrange the numbers in ascending order and then locate the middle value. If there is an odd number of values, the median is the middle number. If there is an even number of values, the median is the average of the two middle numbers.

Arranging the given set of numbers in ascending order: {4, 5, 8, 11}

Since the set has an even number of values, the median is the average of the two middle numbers. In this case, the two middle numbers are 5 and 8. To find the average, we add these two numbers and divide by 2:

(5 + 8) / 2 = 13 / 2 = 6.5

Hence , the median of the given set {4, 5, 8, 11} is 6.5
